Airpax LMLK1-1RLS4-52-30 Miniature Circuit Breaker

Airpax LMLK1-1RLS4-52-30 is a single-pole, hydraulic-magnetic miniature circuit breaker designed for panel-mount installation in DC circuits up to 65 V. It carries a 30 A rating and a 7.5 kA interrupting capacity, providing rapid disconnection under fault conditions; the unit uses a manual reset handle and is non-illuminated for clean panel integration. The device features stud termination and a panel-mount design, weighing about 90 g, making it suitable for compact enclosures where space is at a premium. Hydraulic-magnetic trip technology combines fast magnetic action with a hydraulic delay to minimize nuisance trips on short overloads, enhancing reliability in servo drives, instrumentation, and other DC protection scenarios. Manufactured by Airpax, a Sensata Technologies brand, this model is part of the LMLK1 family and is configured in the -52-30-0-A-01-V variant to meet common 30 A, 65 V DC protection needs in instrumentation, control panels, and other low-profile power-distribution applications. Designed for reliable operation in compact industrial environments.
